AprilAire ARNHPF Radon Mitigation Fan Kit, 117 CFM with 3.5" Outlet Opening

AprilAire helps make your home a Healthy Air environment with the ARNHPF 3-in. Radon Mitigation Fan. Specially designed for use with moderate to tight soil under and around the foundation, this is the dependable way to deal with elevated radon levels around your new or existing home. It's capable of creating high static pressure to ensure constant airflow underneath the foundation, which is necessary when the soil is more tightly packed. The quiet, energy-efficient fan connects to PVC piping installed in the soil underneath your home, and draws up radon gas to safely exhaust outdoors before it can accumulate in your home. Plus, the fan's patent-pending design has sealed seams to prevent radon leakage. The AprilAire Radon Mitigation Fan is built to last for both indoor and outdoor installation, and its housing resists discoloration to stay white over time. It also boasts a water-hardened, motorized impeller, and a thermally protected motor for long-term, reliable radon protection.
